Handheld Cleaner Terminal Design for Slide-Coupled Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handy cleaners face challenges in assembling due to the difficulty in combining PCBs and connecting wires, especially given their small volume and the need to supply power and control signals to the motor.
Innovation Solution
A cleaner design that separates power and control signal wires, using slide-coupled handle and main body terminals for easy assembly without manual connection of terminals, allowing for reduced wire size and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If power and control signal wires are combined in the same connector, then the electrical connection is complete, but the terminal size increases and assembly complexity increases
Solution Approach 1:
The patent divides the electrical connection into separate power transmission terminals and control signal terminals. The power wire and control signal wire are physically separated and connected through distinct terminal structures, reducing the overall terminal size and simplifying the assembly process by allowing independent connection of each wire type.
2Volume of moving object
If the cleaner is designed with small volume, then portability is improved, but the assembly of PCB and wire connections becomes difficult
Solution Approach 1:
The patent segments the electrical connection system into separate power and control signal pathways with dedicated terminals. This segmentation allows for simplified assembly procedures that are particularly beneficial in compact devices where space for assembly operations is limited, making the manufacturing process easier despite the small volume constraint.
3Productivity
If manual connection of terminals is required, then electrical connections can be established, but assembly time increases and assembly difficulty increases
Solution Approach 1:
The patent designs the terminal structure to enable automatic connection when the handle unit is coupled to the main body. The power wire and control signal wire terminals are positioned and configured to connect automatically through the coupling action, eliminating the need for manual wire connection operations and significantly improving assembly speed and ease.
